The generated catalog pages rendered the "Source" accordion title as a
JSX expression, `<Accordion title={`name.html`}>`. Mintlify's search
indexer stringifies expression attribute nodes rather than evaluating
them, so every one of the 399 catalog pages surfaced its Source section
in search results as "[object Object]" (visible on the Scroll Feed page,
among others).
The template literal carried no escaping benefit: every title is a
single-segment `name.html` path, and a double-quoted JSX string handles
it directly. Introduce `mdxStringAttribute`, which emits a plain
`name="value"` attribute and escapes `& " < { }` as HTML character
references (MDX decodes references inside quoted attribute values, and
unlike JSON.stringify it does not rely on backslash escapes, which JSX
strings do not honour). Use it for both the Source accordion title and
the preview iframe title, and regenerate the catalog pages.
Regenerated with `npx tsx scripts/generate-catalog-pages.ts`; the only
change across the 399 pages is the one Accordion title line each.

scramble-reveal: HyperFrames video primitive (text effects / reveal)
|
|
|
|
A target string begins as deterministic wrong glyphs, then resolves one
|
|
character at a time from left to right. Every visible frame comes from one
|
|
fixed-seed LCG table built before the timeline is registered.
|
|
|
|
Variables:
|
|
- text (string, default "HYPERFRAMES"): the target string.
|
|
- accent (green | blue | violet, default "green"): text and frame color.
|
|
- style (terminal | clean, default "terminal"): optional terminal frame.
|
|
- exit (none | fade | up, default "none"): optional departure.
|
|
|
|
Envelope, fixed IN and OUT with elastic HOLD only:
|
|
IN_BASE = 1.65s, curved arrival and the complete left-to-right lock
|
|
HOLD = max(0, D - IN - OUT), subtle drift followed by 0.30s stillness
|
|
OUT_BASE = 0.45s departure when exit is fade or up, 0s when exit is
|
|
none (the default: the locked string holds until the cut)
|
|
If D is shorter than IN_BASE + OUT_BASE, IN and OUT compress together.
|
|
The timeline is never time-scaled.
|
|
|
|
Determinism: frameTable is computed exactly once during synchronous
|
|
timeline construction from fixed LCG seed 0x27c0ffee. Timeline sets only
|
|
read authored rows from that table, so repeated or reverse seeks produce
|
|
the same string for the same time.
|
|
|
|
Mount contract: the runtime clones only this template. #root fills the host
|
|
box, establishes the container query basis, has no data-width or data-height,
|
|
and registers one paused timeline under the literal scramble-reveal key.

## Paste it into your composition
|
|
|
|
Open `compositions/components/scramble-reveal.html` and copy what is inside into your own composition.
|
|
|
|
A component has no size or duration of its own. It takes both from the composition
|
|
you paste it into.
|
|
|
|
## Variables
|
|
|
|
Every one of these has a default, so the piece works untouched. Set the ones you
|
|
want to change on the element:
|
|
|
|
| Variable | Default | Accepts | What it does |
|
|
| --- | --- | --- | --- |
|
|
| `text` | `HYPERFRAMES` | string | Target string that resolves from deterministic wrong glyphs. |
|
|
| `accent` | `green` | `green`, `blue`, `violet` | Color used by the text, prefix, and optional terminal frame. |
|
|
| `style` | `terminal` | `terminal`, `clean` | Terminal frame or clean text-only presentation. |
|
|
| `exit` | `none` | `none`, `fade`, `up` | Optional departure. Default none: the locked string holds until the frame cuts. |
|
|
|
|
Set them with `data-variable-values` on the element that mounts it. These are the
|
|
defaults, so this behaves exactly like the preview above until you change one:
|
|
|
|
```html wrap
|
|
<div
|
|
data-composition-id="scramble-reveal"
|
|
data-composition-src="compositions/components/scramble-reveal.html"
|
|
data-variable-values='{"text":"HYPERFRAMES","accent":"green","style":"terminal","exit":"none"}'

></div>
